50xx motor mounting size?

Hi what are the mounting distances (1 and 2) on 50xx motos? I cant find anywhere… Thank you !


Should be 30mm

30mm is the 1 . And the 2 ?

If you know the radius (15mm) and it’s a 90°angle, then you can calculate the distance between them 21.2mm


It seems like the racestar motors used an odd pattern, i think it’s like 38mm across

Screenshot_20190217-184612~2 38 is like outside diameter but not the can itself

I love high school math.
